LSM error function In e1@.Data - e2

[19anita89]

In the LSM function I get an error:

Error in eval (call, parent.frame ()):
dims [product 8] do not match the length of object [10]
In addition: Warning message:
In e1 @ .Data - e2:
longer object length is not a multiple of shorter object length

when I look for where the error is, I find that it is here:

diff <- sum (abs (harvest (stock) [, ac (range (stock) ["maxyear"])] - Fnew))

Thank you for helping me with this error.

The function assumed the wrong dimensions for the stock object. The tutorial has now been corrected, but let me know if it works for you.

Dear Iago, Thanks for the quick reply. I work with the Package FLAssess the LSM function. I ran the tutorial but the error is continuous. Yes, the assumed different dimensions for the objects: [image: image.png] In this case I have the information structured by 9 age (with plus group), and 21 years (annex files) and one CPUE index. The CPUE index have structurer annually and the catch have by age This issue can be related to the CPUE index because it is n't structured by age? We have a Survey index but the problem if with has missing years in the index (Ex. 1996-2016, the missing years are 1998, 2006, 2009, 2014 and 2015). I appreciate your help with this error.

Yes, the example there assumes the index is structured by age. Not sure if there are implementations of the method for a biomass index, but should be possible to derive it once some assumption on selectivity is made,
